Defeuling question

I put in my mini maxx and installed my 5" exhaust last night.

I took it around town today. It was defueling A LOT. Looked like the pyro was reading way high. Like 2400. I didn't do an egr delete, so were is it getting these egt readings from??

I think I read some where before that if you do exhaust delete and don't do the egr delete with pyro them you have to set up your pyros on the mini maxx a certain way because you'll get erroneous reading and constantly defuel. Does anyone know??

I had the same thing happen after setting mine up. I did not do the egr delete either so, if I remember correctly, it is recommended to turn off the defueling setting for the pyro in this case. That way it will not be in constant defuel. I have also heard unless you are putting a HUGE load on the engine the egt's should not reach a dangerous level. But I would still recommend setting the other defueling levels up if you haven't already done so, better safe than sorry, eh?
